Christian Schaefer 
@caeferChristian was a developer and architect for about 12 years working for different companies from web agencies to portals to publishers mostly dealing with PHP. Then he changed sides and now represents the client and rather than implementing requirements he now defines them. If that makes him the best or the worst client you can think of is up to you to decide.
